A New Proposal of Smart Lighting System Based on Radar and Camera Sensors for Smart City

Despite the development of sensors and LED lighting technologies, smart lighting technology is a still challenging topic. No smart lighting system with built-in RADAR and camera has yet been reported that is both energy-saving and efficient for searching for missing persons. Herein we design a smart lighting system based on RADAR and a camera sensor. The RADAR detects moving obstacles including pedestrians and the camera records by means of RADAR motion detection in event mode. Selected images corresponding to persons of interest are very useful for quick searching for missing persons.
